Sample files included with the product use '.' as decimal separator. If your international settings uses a different decimal separator, floating point numbers in the samples will have to be adjusted. i123 is a very capable spreadsheet program but don't expect the same set of functions and capabilities found on well known spreadsheets for Windows/MacOS. The current version is limited to 26 columns and 99 rows, it does not support absolute cell references ($B$3) and has limited support for date/time functions. Future releases will include more functions and address these limitations. Plase visit i123's home page (www.ttrix.com) for a complete list of functions and capabilities. You can also watch a flash movie of i123 in action.
